目的通过对南安市乡镇居民送检的413份分散式供水的实验测定结果进行汇总分析,总结南安市居民用水现状,对存在问题进行分析并提出。方法按生活饮用水国标方法对(井水、山泉水)样品的常见指标(包括4个感官性状指标,8个一般化学指标以及6个毒理学指标等项目)进行检测。结果南安市乡镇分散式供水常见指标中毒理学测定结果以及感官性状各项指标的合格率都较高,然而其中的一般化学指标合格率较低为55.7%,特别是pH,超标率高达39.9%。结论居民应以集中式供水作为生活饮用水的首先,政府及相关部门应重点修建新的水厂和管网系统,从而满足居民用水的需求。
Objective To summarize and analyze the experimental results of 413 decentralized water supplies submitted by township residents in Nan’an City, summarize the current status of water use for residents in Nanan City, and analyze the existing problems. Methods According to the national standard method of drinking water, the common indexes (including four sensory traits, eight general chemical indexes and six toxicological indexes) of samples of well water and mountain spring water were tested. Results The results of toxicological measurements of common indicators of decentralized water supply in villages and towns in Nanan City were high and the passing rates of various indexes of sensory traits were high. However, the pass rate of general chemical indicators was 55.7%, especially the pH was over 39.9%. Conclusion Residents should use centralized water supply as their drinking water. First, the government and relevant departments should focus on the construction of new waterworks and pipe network systems to meet the needs of residents.
